Li works at a printing company. for her first year, her salary was $21,000. for her second year, her salary was $22,500, and for her third year her salary was $24,000. using the pattern predict the amount of money li will earn in her fourth year

$25,500.

Step-by-step explanation:

We have been given that Li works at a printing company. for her first year, her salary was $21,000. for her second year, her salary was $22,500, and for her third year her salary was $24,000.    

Let us find the difference between consecutive salaries for two years.    

We can see that every next year Li's salary increases by $1500.

So Li's salary for 4th year will be $1500 more than the salary for her 3rd year salary.

Therefore, Li's salary for 4th year will be $25,500.
